Main functions doesn't do any input checking on `data` argument

[EmilHvitfeldt]

sooo, there isn't much input checking for some of the main functions here in {rsample}, to the point of bootstraps(bootstraps) not returning an error 😬

bootstraps

library(rsample)

mat_cars <- as.matrix(mtcars)

bootstraps(mat_cars, times = 2)
#> # Bootstrap sampling 
#> # A tibble: 2 × 2
#>   splits          id        
#>   <list>          <chr>     
#> 1 <split [32/11]> Bootstrap1
#> 2 <split [32/11]> Bootstrap2

bootstraps(1:10, times = 2)
#> # Bootstrap sampling 
#> # A tibble: 0 × 2
#> # ℹ 2 variables: splits <list>, id <chr>

bootstraps(NULL)
#> # Bootstrap sampling 
#> # A tibble: 0 × 2
#> # ℹ 2 variables: splits <list>, id <chr>

bootstraps(lm(mpg ~ disp, data = mtcars))
#> # Bootstrap sampling 
#> # A tibble: 0 × 2
#> # ℹ 2 variables: splits <list>, id <chr>

vfold_cv

library(rsample)

mat_cars <- as.matrix(mtcars)

vfold_cv(mat_cars)
#> #  10-fold cross-validation 
#> # A tibble: 10 × 2
#>    splits         id    
#>    <list>         <chr> 
#>  1 <split [28/4]> Fold01
#>  2 <split [28/4]> Fold02
#>  3 <split [29/3]> Fold03
#>  4 <split [29/3]> Fold04
#>  5 <split [29/3]> Fold05
#>  6 <split [29/3]> Fold06
#>  7 <split [29/3]> Fold07
#>  8 <split [29/3]> Fold08
#>  9 <split [29/3]> Fold09
#> 10 <split [29/3]> Fold10

vfold_cv(1:10)
#> Error in if (v > max_v) {: argument is of length zero

vfold_cv(NULL)
#> Error in if (v > max_v) {: argument is of length zero

vfold_cv(lm(mpg ~ disp, data = mtcars))
#> Error in if (v > max_v) {: argument is of length zero
